The Radeon X1300 Pro Reference Board from ATI

We disassembled the video card heatsink to take a look, see Figure 4. As you can see, the entire heatsink is made of copper.

This video card uses eight GDDR2 256-Mbit 2.5 ns chips from Infineon (HYB18T256161AF-25)to give it 256 MB of video memory (256 Mbits x 8 = 256 MB). These chips can run up to 800 MHz. Since this video card accesses the memory at 800 MHz there is no room for memory overclocking inside the memory’s specifications. But of course you can try overclock it over its specs. Keep in mind that we are talking about a pre-production sample; the final model from ATI partners can use a different memory chip model.

The reference board doesn’t have video capture function (VIVO). However, as you can see on the left hand side in Figure 4, there is a place on the board to have an ATI Rage Theater chip soldered in the future, if an ATI partner wants to release a model with VIVO function.
